Joint Enclosures
FIBER OPTIC JOINT CLOSURE INLINE TYPE (MOD-J28M)
The MOD-J28M Inline Fiber Optic Joint Closure is a compact, durable, and high-performance closure designed to protect fiber splices in aerial, duct, and direct-buried installations. With its robust PP + GF (Polypropylene + Glass Fiber) construction and IP68 protection level, it ensures long-term reliability in harsh outdoor environments.
Its inline rectangular design makes it ideal for straight-through and branching connections, while modular splice trays allow flexible capacity up to 48 fibers.
